Description

[Detailed Description of the Invention] The present invention is configured to combine and transport cut stem culms from a plurality of transport routes, each of which is equipped with a transport device, and between the transport devices,
A fixed guide for guiding the conveyed stem culm to the merging route is provided, and two elastic auxiliary guide rods for pressing the stem culm toward the conveying device are provided with their free ends positioned on the merging route side. Regarding the stem culm conveying device of the machine.

In this type of device, each of the conveying devices is configured to ensure reliable conveyance by the action of the auxiliary guide rod even when the amount of conveyed stem culms is small.
In order to guide the conveyed stem culm to the merging route, the free end side of each guide rod is extended to the merging route side from the action end position of the fixed guide, for example, during reaping work near the edge of a ridge. , when the amount of conveyed stem culms on one side of the conveying device increases,
There was a problem in that the guide rod pressed by the stem culm entered the path of another conveying device, causing trouble in conveying the stem culm in the other conveying device.

In view of the above points, the present invention has been developed to avoid problems in conveying stem culms due to displacement of the guide rod due to an increase in the amount of conveyed stem culms, and to guide stem culms well to a converging route. The purpose is to make it possible to

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A pair of left and right lifting devices for lifting planted stem culms in the field 1.1.
A reaping device 2 that reaps the raised stem culms, a pair of left and right conveying devices 3, 3 that convey the cut stem culms between the two lifting devices 1, 1 toward the center and merge them, and a pair of left and right conveying devices 3, 3 that transport the merging stem culms to the rear of the machine. A vertical conveying device 5 that changes its posture to a sideways posture while conveying it upward and delivers it to the feed chain 4, and a threshing unit 6 that performs threshing and sorting while conveying the stem culm by the feed chain 4 are sequentially operated. It is equipped with a crawler traveling device 7 and is connected to a traveling vehicle body equipped with a control section 8, so that the reaper can be used to continuously harvest planted stems and culms in the field as it travels. A combine harvester is used as an example.

A fixed guide 9 having a substantially rhombic shape in plan view is provided in series between the conveying devices 3, 3, and is configured to guide the conveyed stem culm toward the merging path R by the vertical conveying device 5.

Elastic auxiliary guide rods 10 having approximately the same longitudinal length as the fixed guide 9 are disposed on both left and right sides of the fixed guide 9.
10 is at a position approximately at the same height as the outer edge of the fixed guide 9,
One end thereof is fixed to the starting end of the fixed guide 9, and the free end thereof is horizontally spaced apart from the side surface of the fixed guide 9 toward the rear, and corresponds to the conveying devices 3, 3. Even when the amount of stem culms to be conveyed is small, the stem culms are pressed against the conveying devices 3, 3 by their elastic displacement, and the stem culms can be surely conveyed.

Each of the guide rods 10, 10 is in the maximum displacement state due to the pressure of the stem culm, and its free end side is configured to be close to the working end of the fixed guide 9.
The structure is such that it does not protrude into the stem culm transfer path on the other side of the stem.

A wire rod guide 11 that can be elastically displaced left and right is extended from the working end of the fixed guide 9 toward the starting end of the merging path R, and the guide 11 is made of a wire and can be elastically displaceable from side to side. It is configured to be guided and conveyed toward the merging route R while elastically displacing left and right according to the amount of stem culms.

In summary, the present invention provides a fixed guide 9 that is approximately rhombic in plan view and that guides the conveyed stem culm to the merging route R between the conveying devices 3 and 3.
, and elastic auxiliary guide rods 10.10 having approximately the same longitudinal length as the fixed guide 9 are provided on both left and right sides of the fixed guide 9, and the elastic auxiliary guide rods 10.10
is located at approximately the same height as the outer edge of the fixed guide 9, one end thereof is fixed to the starting end of the fixed guide 9, and the other end is horizontally spaced apart from the side surface of the fixed guide 9 toward the rear. The guide is disposed so as to be inserted into the locus of the stalk culm conveying action of the conveying devices 3, 3, and is elastically displaceable left and right from the terminal end of the fixed guide 9 toward the starting end side of the merging route R. A feature is that the guide 11 made of wire is extended.

In other words, in each of the conveying devices 3, 3, even if the amount of conveyed stem culm increases and the guide rods 10, 10 are displaced, the fixed guide 9 will counteract the pressing force of the stem culm due to the increase in volume. Therefore, further displacement of the guide rods 10, 10 is prevented, and the guide rods 10, 10 are
, 3 is prevented from entering into the path of the stem culms, thereby making it possible to avoid problems in the transportation of the stem culms due to the displacement of the guide rods 10 and 10 due to the increase in the amount of stem culms.

Moreover, from the working end of the fixed guide 9 to the wire guide 11
is extended toward the merging route R, so both conveyance devices 3, 3
The stem culms can now be guided to the merging route R without being displaced left or right according to the amount of stem culms transported by each, and the culms can be smoothly guided to the merging route R while avoiding transportation troubles caused by the displacement of the guide rods 10, 10. The stem culm can be transported to the route R successfully regardless of the amount of the stem culm.
